मैंने इसे अपने तरीके से किया था। (इतना बैश कोड के लिए खेद है)

और print_bar
एक फ़ंक्शन है, जो एक रंगीन प्रतिशत बार उत्पन्न करता है:
function print_bar() {
prcntg=$1
warn=$2
crit=$3
bar_color=$COLOR_OK
if [ $prcntg -gt $warn ]; then
bar_color=$COLOR_WARN
fi
if [ $prcntg -gt $crit ]; then
bar_color=$COLOR_CRIT
fi
bar_width_fill=$((BAR_WIDTH * prcntg / 100))
bar_width_empty=$((BAR_WIDTH - bar_width_fill))
printf -v bar "%${bar_width_fill}s" ""
printf -v nbar "%${bar_width_empty}s" ""
printf "${bar_color}"
printf '%3d%% %s' "$prcntg" "${bar// /█}"
printf "${COLOR_NONE}"
printf '%s' "${nbar// /▒}"
}
